Abstract
Abstract A method of making electrical contacts (10) for either tin or gold-plating without changing the overall dimensional shape of the contact (10) has been disclosed. The method includes the step of providing a given spring rate for a pair of cantilever beams (26) by cutting the beam (26) to a predetermined width without changing the length thereof.

Claim 1
Independent Claim
103 words
A method of making an electrical socket contact for either gold plating or tin plating without changing the length of the socket contact, said method comprising the steps of: blanking out of contact outline comprising a wire barrel at one end and a pair of parallel beams at another end and varying the width of said beams to produce either a high spring rate for tin plating or a low spring rate for gold plating without a change in the length of said beams; and rolling said contact outline into a cylindrical form with said beams defining a socket for receiving a pin.
Claim 2
Independent Claim
